Secretary of State Delbert Hosemann is calling for an investigation of some election literature that has been mailed before the Tuesday primary election.

Hosemann, in a Wednesday news conference, said in the cases brought to his attention, some people appear to have broken a state law that bars anonymous mailers. He said other groups have registered with his office but show no campaign collections or expenditures, despite having sent out fliers.

Attorney General Jim Hood's office said it will investigate. Hosemann said violations are misdemeanors, punishable by fines of up to $3,000 and up to 6 months in jail.

Most literature presented by Hosemann criticizes incumbent Republican lawmakers, claiming they oppose gun rights and the current state flag, while supporting Common Core education standards and federal health care reform.
